Answer:
Outgoing
Step-by-step explanation:
Recluse is a mental state in which someone withdraws from friends, people and social gatherings. The affected person lives a solitary life and tends to avoid other people.
The question asks us to find an antonym (the opposite in meaning) to recluse that can be used to find its meaning. If someone is not living a solitary life or withdrawn from people, then the person is outgoing. So, the appropriate antonym that best define recluse as used in the question is outgoing.
